Just use -lpthread (-lkse) or -lthr. >=20 Oh, I thought that the intent was to be able to write -lc_r and have the linker pick up another (modern) threaded library. If that is just to support -pthread, I also think that the latter should just be nuked. It is similarly news to me that -pthread is still alive; I thought we killed it months ago.
